Bug #: 40881
Summary: GeoCoordinateValue is to simple
Product: MediaWiki extensions
Version: unspecified
Platform: All
OS/Version: All
Status: NEW
Severity: normal
Priority: Unprioritized
Component: DataValues
AssignedTo: wikibugs-l@lists.wikimedia.org

Classification: Unclassified
Mobile Platform: ---
The implementation of GeoCoordinateValue (Change Ia084e73a: Implemented
GeoCoordinateValue) seems to make an assumption about a perfect sphere, ie. the
implementation is really just polar coordinates with adjusted names for the
coordinates.
The implementation should refer to a valid datum, and only assume a perfect
sphere if the datum is missing.
Also note that use of altitude normally refer to a standard surface, and
without a valid datum this can't be deducted. Use of elevation is more
appropriate in this cases.
In my opinion the naming of the class is misleading as it is now.
See also Geographic coordinate system
(http://en.wikipedia.org/wiki/Geographic_coordinate_system)
In addition there should be methods for transformation between different datums
and coordinate systems, but this can be done in Lua if the necessary data is
available.
